Dar is a shell command that makes backup of a directory tree and files. Its features include splitting archives over several files, DVD, CD, ZIP, or floppies, compression, full or differential backups, strong encryption, proper saving and restoration of hard links, extended attributes, file forks, Door inodes, and sparse files, remote backup using pipes and external commands (such as ssh), and rearrangement of the "slices" of an existing archive. It can run commands between slices, before and after saving some defined files or directories (for a proper database backup, for example), and quickly retrieve individual files from differential and full backups. Several external GUIs exist as alternatives to its CLI interface, like kdar, DarGUI, SaraB, etc.

Zero Install is a decentralized cross-distribution software installation system. It allows software developers to publish programs directly from their own Web sites, while supporting features familiar from centralized distribution repositories such as shared libraries, automatic updates, and digital signatures. It is intended to complement, rather than replace, the operating system's package management. 0install packages never interfere with those provided by the distribution.

CheckInstall keeps track of all files installed by
a "make install" or equivalent, creates a
Slackware, RPM, or Debian package with those
files, and adds it to the installed packages
database, allowing for easy package removal or
distribution.

ISO Master is an easy to use GUI CD image editor for Linux, BSD, and Windows. Basically, you can use this program to extract files from an ISO, add files to an ISO, and create bootable ISOs, all in a graphical user interface. It can open both ISO and NRG files, but can only save as ISO. It is based on bkisofs, a library for reading, modifying, and writing ISO images.

mkisofs is used for premastering iso9660 filesystems which are used on CDROMs. The output of mkisofs can then be sent to a CDROM writer with a utility such as cdrecord. It has support for many formats, including Rock Ridge, Joliet, and Apple HFS (beta).

AutoUpdate is a Perl script which performs a task
similar to Red Hat's up2date or autorpm. It can be
used to automatically download and upgrade RPMs
from different HTTP(S) or (S)FTP sites, while also
handling dependencies. Moreover, it can also be
used to keep a server with a customized (Red Hat)
distribution plus all clients up to date.

slapt-get is an APT-like system for Slackware
package management. It allows you to search
Slackware mirrors and third-party package sources
(such as www.linuxpackages.net) for packages,
compare them with installed packages, and install
new packages or upgrade installed packages, all
with a few simple commands.

BitRock InstallBuilder allows you to create
easy-to-use multiplatform installers for Linux
(x86/PPC/s390/x86_64/Itanium), Windows, Mac OS X, FreeBSD, OpenBSD, Solaris (x86/Sparc), IRIX, AIX, and HP-UX applications. The generated application installers have a native look-and-feel and no external dependencies, and can be run in GUI, text, and unattended modes. In addition to self-contained installers, the installation tool is also able to generate standalone RPM packages.

AutoRPM is a program that can do any combination of the following: mirror RPMs from an FTP site, keep installed RPMs consistent with an FTP site or local directory and keep installed RPMs in a cluster or network of systems consistent. It is highly flexible and contains a fully command-line driven interactive install mode (for installing RPMs from the queue or for installing RPMs from your system interactively). It also handles recursive dependencies, multiple versions of the same RPM, the same RPM with multiple architectures, and more. It does some of the same tasks as up2date and AutoUpdate.
